Project: Costs and Benefits of Traffic Policies Which Reduce Noise Nuisance

Reference: H109

Last update: 30/10/2003 12:41:22


A new noise database and contour maps will be produced under this project and these will reflect the impact of the different policy scenarios. The underlying noise database will be linked to a residential property database to show which areas would experience changes in noise levels under each scenario. The impact of these changes will be evaluated using cost-benefit analysis. This will include the benefits of noise reduction calculated by applying the monetary value for noise being generated by the sister project (H109C).


This research will assess the relative merits of a number of different hypothetical traffic management options aimed at reducing transport related environmental noise in Birmingham. The project builds on work carried out between 1997 and 1999 by Birmingham City Council's Environmental Services Department (BESD), when they produced the UK's first sound emission contour maps. Birmingham City Council will undertake some support work on this project.
This project is intended to tie in with a forthcoming EU directive on environmental noise. The directive is likely, amongst other things, to require member states to produce noise maps, (initially for large urban areas) to show the extent of the noise problem. Then based on these maps they will be required to draw up local action plans to reduce the noise nuisance. This project will demonstrate how these maps can be used to assess the relative merits of a small selection of hypothetical mitigation measures.

Summary of results

  1. The study aimed to show how transport models and noise maps could be used together to appraise the relative merits of noise reduction policies. The project delivered what was expected. The framework worked and the results were good and credible.
    The study showed that it is possible to use transport models and noise maps together to assess what transport management options could help reduce noise, whilst making an assessment of the other transport impacts too. The study looked at two hypothetical transport options for Birmingham in order to see whether it was possible.
